Genetic Testing Q & A

What does genetic testing have to do with cancer?

Genetic testing determines your risk for some types of cancer by detecting mutated genes. These tests detect inherited genes, allowing you to take aggressive steps to prevent cancer if necessary. 

Your genes can also mutate or change throughout your lifetime. This type of acquired gene mutation causes cancer more often than inherited mutations.

After you receive a cancer diagnosis, your doctor at Choice Cancer Care may do another type of gene testing called tumor DNA sequencing. This test shows genetic changes that guide your treatment.

What cancers commonly occur due to inherited genetic mutations?

You may inherit a tendency to develop many types of cancer. You can also inherit a high risk for a specific type of cancer. The two most common examples include:

BRCA mutations

Inherited mutations in the BRCA1 or BRCA2 genes significantly raise the risk for breast and ovarian cancers in women. BRCA mutations also affect men and women, putting them at a higher risk of male breast cancer, pancreatic cancer, prostate cancer, fallopian tube cancer, and primary peritoneal cancer.

Lynch syndrome

Another inherited condition, Lynch syndrome, seriously raises your risk for colon cancer. It also increases your chances of endometrial cancer and cancers of the ovaries, stomach, small intestine, pancreas, kidney, and brain.

Should I consider genetic testing?

You should talk with the team at Choice Cancer Care about genetic testing when:

  • Several first-degree relatives have cancer
  • Many relatives on one side of the family have the same cancer
  • Family members have multiple types of cancers linked to one genetic mutation
  • Family members had cancer at a younger age than normal for that cancer
  • A family member has more than one type of cancer
  • A family member has a rare cancer
  • Your ethnicity raises your risk for specific cancers
  • Other family members had genetic testing that found a mutation
  • You have known physical risks, such as exposure to sunlight or a history of colon polyp

The Choice Cancer Care team helps you determine if you should get genetic testing based on your history and National Comprehensive Cancer Network (NCCN) guidelines.

Your provider also talks with you about the process of testing, including your options for preventive treatment if you test positive for a genetic mutation.
